"A wonderful classic British preserve. Spread it thickly on fresh baked bread, crumpets, muffins or hot buttered toast. It's also delicious on pancakes and if used as a filling for cakes or tarts - such as my Easy Peasy Lemon Squeezie All-In-One Lemon Drizzle Cake!. This recipe has the benefit of being made in the Crock Pot/Slow Cooker, acting as a bain marie which allows you time to being doing other things in the kitchen! I have also given instructions for the more traditional method if you don't have a slow cooker. A jar or two makes a lovely gift - tie a pretty ribbon around the neck of the jar and provide a recipe tag as well. We like our lemon curd quite tangy - so if you are not keen on a very lemony taste - increase the sugar by about 2 to 3 ounces, or use 2 lemons only. This can also be made with oranges or limes, or a mixture of all three Citrus fruits; it will then be called St.Clement's Curd, from the Nursery Rhyme "Oranges and Lemons - The Bells of St.Clements". (This recipe was adpated from The National Trust Cookbook, hence the title of this lemon curd recipe!)..."
